Specifying frequency setpoints
The frequency setpoint value can be assigned in one of three ways,
dependent on PNU A01:
• via the installed potentiometer on the keypad,
PNU A01 = 00;
• via analog input O (0 to 10 V) or OI (4 to 20 mA),
PNU A01 = 01 (WE);
• via PNU F01 or PNU A20, PNU A01 = 02.
Selecting fixed frequencies
X The set fixed frequency values are selected by activating the
respective digital inputs (a Table 13).

If one or more of the fixed frequencies exceeds 50 Hz, you
must first increase the end frequency accordingly with
PNU A (04 (a Section ”Maximum end frequency”,
Page 79).

Fixed frequency stage 0 (none of the inputs FF1 to FF4 are
activated) corresponds to the frequency setpoint value.
Depending on the configuration PNU A01 it is possible to
implement via the integrated potentiometer, the setpoint
input values O or OI, or via PNU F01 and PNU A20.
